摘要
本文根据作者的PLC应用实践,借鉴高级语言的编程方法,从人机接口入手,自顶向下的分析程序结构,对PLC的结构化编程进行了探讨。
This paper is based on the author＇s experience in application of PLC. The method of structured programming of PLC that use for reference the method of programming in high-level language is discussed. The structured is obtained from the interface be- tween the human and the machine by topdown analyzing.
